Fig 8. CV standard error of mean.

Bar Plot of the Coefficient of Variation (%) with error bars representing the standard error of the mean (SEM) of BFI, StO₂, THC for each subject for all four measurements in both manual (red) and chassis (blue) methods. No statistically significant differences in CV were observed between methods. Abbreviations: BFI, blood flow index; StO₂, tissue oxygen saturation; THC, Total Hemoglobin Concentration.
